US singer and comedian Oliver Tree is believed to be among six people who died when two helicopters collided over Rio de Janeiro, crashing in the city's western zone.
Rio de Janeiro's Military Fire Department said that one of the helicopters crashed on Sunday into the parking lot of a car dealership, where several electric vehicles were parked, igniting a fire that was extinguished.
Officials said an investigation was underway to determine the cause of the collision.
Police said 32-year-old Tree was on the list of passengers handed to aviation authorities but the bodies had yet to be formally identified.
Recognisable by his signature bowl cut, Tree was known for his songs Life Goes On and When I'm Down.
He released his fourth studio album, Love You Madly, Hate You Badly in April.
